scope:

1.1 These test methods cover the chemical analysis of ferroniobium having chemical compositions within the following limits:

  Element Composition, %
  Aluminum 2.00 max
  Carbon 0.30 max
  Chromium 2.00 max
  Cobalt 0.25 max
  Lead 0.01 max
  Manganese 3.00 max
  Niobium 40.00 to 75.00
  Phosphorus 0.05 max
  Silicon 4.00 max
  Sulfur 0.03 max
  Tantalum 7.00 max
  Tin 0.15 max
  Titanium 5.00 max
  Tungsten 0.50 max

1.2 The test methods appear in the following order:

  Sections
Separation of Niobium, Tantalum, and Titanium by the Ion-Exchange Test Method 15 and 16
   
Titanium by the Spectrophotometric Test Method [0.05 % to 5.0 %] 17 - 21
   
Niobium by the Gravimetric Test Method [40 % to 75 %] 22 - 23
   
Tantalum by the Gravimetric Test Method [1 % to 7 %] 24 - 25
   
Tantalum by the Spectrophotometric Test Method [0.25 % to 1 %] 26 - 30

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6, and specific warning statements in 11.1.
